How to implement a XAML Radio Button control with an ObservableCollection source?

Question

I have the following ComboBox element in XAML:

<ComboBox ItemsSource="{Binding CollectionControlValues}"
    SelectedItem="{Binding CollectionControlSelectedValue, UpdateSourceTrigger=PropertyChanged}">
    <ComboBox.ItemTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding Value}" />
        </DataTemplate>
    </ComboBox.ItemTemplate>
</ComboBox>

I would like to implement RadioButtons in the same way, like this:

PSEUDO-CODE:

<RadioButtons ItemsSource="{Binding CollectionControlValues}"
    SelectedItem="{Binding CollectionControlSelectedValue, UpdateSourceTrigger=PropertyChanged}">
    <RadioButtons .ItemTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding Value}" />
        </DataTemplate>
    </RadioButtons .ItemTemplate>
</RadioButtons >

However, the only WPF RadioButton implementations I can find are static like this.

<StackPanel x:Name="rbHolder1" Style="{StaticResource rbStackPanelStyle}">
    <RadioButton Style="{StaticResource rbStyle}">RadioButton 1</RadioButton>
    <RadioButton Style="{StaticResource rbStyle}">RadioButton 2</RadioButton>
    <RadioButton Style="{StaticResource rbStyle}">RadioButton 3</RadioButton>
    <RadioButton Style="{StaticResource rbStyle}">...</RadioButton>
</StackPanel>

How can I create a RadioButton control which is not static like the above but instead gets its data from its ItemsSource property as in the above ComboBox example?

Answer 1

Use ItemsControl and DataTemplate:

<ItemsControl ItemsSource="{Binding CollectionControlValues}">
  <DataTemplate>
    <RadioButton Content={Binding Value} IsChecked={Binding SomeProperty} GroupName="name"/>
  </DataTemplate>
</ItemsControl>

code in window1.xaml file

< Window

x:Class="RadioButton.Window1"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:sys="clr-namespace:System;assembly=mscorlib"
    xmlns:local ="clr-namespace:RadioButton"
Title="Window1" Height="300" Width="300" Loaded="Window_Loaded">
<StackPanel>
    <StackPanel.Resources>
        <ObjectDataProvider x:Key="RadioOptions" MethodName="GetValues" ObjectType="{x:Type sys:Enum}">
            <ObjectDataProvider.MethodParameters>
                <x:Type TypeName="local:RadioOption" />
            </ObjectDataProvider.MethodParameters>
        </ObjectDataProvider>
        <Style x:Key="RadioButtonList" TargetType="{x:Type ListBox}">

            <Setter Property="BorderBrush" Value="{x:Null}" />

            <Setter Property="BorderThickness" Value="0" />

            <Setter Property="ItemContainerStyle">

                <Setter.Value>

                    <Style TargetType="{x:Type ListBoxItem}" >

                        <Setter Property="Margin" Value="2" />

                        <Setter Property="Template">

                            <Setter.Value>

                                <ControlTemplate TargetType="{x:Type ListBoxItem}">

                                    <Border Background="Transparent">

                                        <RadioButton Focusable="False"

                    IsHitTestVisible="False"

                    IsChecked="{TemplateBinding IsSelected}">

                                            <ContentPresenter />

                                        </RadioButton>

                                    </Border>

                                </ControlTemplate>

                            </Setter.Value>

                        </Setter>

                    </Style>

                </Setter.Value>

            </Setter>

        </Style>
    </StackPanel.Resources>
    <ListBox Margin="37,20,28,58" Name="listBox1" Style="{StaticResource RadioButtonList}" ItemsSource="{Binding Source={StaticResource RadioOptions}}"  />
</StackPanel>

this line

<ListBox Margin="37,20,28,58" Name="listBox1" Style="{StaticResource RadioButtonList}"

ItemsSource="{Binding Source={StaticResource RadioOptions}}" />

is using itemsource property

C# code

namespace RadioButton

{

public enum RadioOption

{

    option1,

    option2,

    option3,

    option4

}

/// <summary>

/// Interaction logic for Window1.xaml

/// </summary>

public partial class Window1 : Window

{
    public Window1()

    {

        InitializeComponent();

    }

}

}

i think this will help you out..
